I just bought skyports (within the last fortnight). Im heaps stoked with them. Really easy to use. So many possibilities. Not having any probs at all.
Here are some examples http://adamrose.wordpress.com/2009/0...s-and-dragons/ (sorry for all the extra info, just scroll to the pics)
For anyone interested these two pics were taken using a 580, skyport and set up. You can tell the direction of flash with the shadows on the dragon. Both of these shots would either have been average or not taken at all with out off camera flash.
If you look at the exif. Youll notice that I had low speeds even when under exposing the ambient 1-2 as well as high . Again Im super happy with the 30ds performance.
Anyone tossing up buying buying skyports. They have my full approval.
